You will get to know more about electrical contact cleaners and how to clean electrical contacts on this page. There are many ways you can clean electrical contacts using contact cleaners such as WD-40, alcohol, white vinegar, nail polish, acetone, and many more.
There is no way you can avoid electrical malfunctioning with your devices when you have dirt around the electrical contacts or rusty. Any form of contaminants can damage the electrical contacts, and you need to clean immediately you notice the malfunctioning.
Cleaning takes lots of caution and attention because you do not want to damage the electrical contacts in the process. Getting the right contact cleaner is the first step, and the right application is the second one. After cleaning, you should also apply a system to help keep the contact-free from future contamination.
What is a contact cleaner?
You are likely to come across many names for contact cleaners such as switch cleaner, electrical cleaner, battery terminal cleaner, or electrical contact cleaner. Whichever name you choose to call it, they all serve the same purpose.
Contact cleaner is a solvent that helps remove contaminants from electrical contacts, switches, electrical components, and conductive surfaces of connectors. Once you apply the contact cleaner, it operates by quickly removing the contaminants.
You need to spray the contact cleaner and ensure the substance gets through to the crevices of the connectors to ensure the device is back to normal for optimal performance.
Why do you need an electrical contact cleaner?
Oxidation contamination, grease, dirt, and dust can interrupt or reduce the current flow in your device, thereby affecting the performance. So, the contact cleaner will help you get rid of the contaminants and ensure that your device can run as it should for optimal results.
How do I remove oxidation and rust?
You can remove rust and oxidation either through mechanical or chemical methods. For sensitive contacts, you can use a brass or steel brush to scrub off oxidation, as it is the common method of doing it.
Scrubbing the areas will do many wonders, but one needs to be careful when doing it to avoid damages to the electrical contacts. In this situation, some cleaner is allowed, which will help you reach out to tight areas to soften the contaminants and ensure your device can work optimally.
Things to look for when choosing contact cleaner
There are some important things that you need to consider when choosing a contact cleaner.
Most of the contact cleaners you will get today to contain alcohol and hydrocarbon solvents, making them highly flammable. The cleaners are very effective, but they pose a high safety hazard which is the reason you should never use them anywhere near open flames or sparks.
So, you should be careful when choosing the contact cleaner and ensure you choose the safe one to use.
If you intend to clean contacts while the power is still on, choose a cleaner with the highest dielectric strength possible. Before spraying anything onto the circuits you’re attempting to clean, always know the amperage and voltage of the circuits you’re attempting to clean, and evaluate the suitability of any cleaner in your application.
The maximum electric field that a material can withstand before its insulating properties degrade is called dielectric strength. In other words, the lower the dielectric strength, the more likely it will break down and allow electricity to flow through it, resulting in a short circuit and/or a major safety issue.
While the contact surfaces of connectors are metal, they are frequently housed in plastic, with rubber gaskets to seal everything from the outside environment. If the solvent used in a contact cleaner is incompatible with the plastic, it can cause small cracks, embrittlement, or softening. Rubber seals may swell, shrink, or even dissolve if exposed to a harsh solvent.
How to clean corroded electrical contacts?
The best way you can clean corroded electrical contacts, you can make use of contact cleaner spray. The Hosa D5S-6 CAIG DeoxIT 5% Spray Contact Cleaner is a good one to consider if you are on the lookout for a cleaner for your corroded electrical contacts.
You should spray the content of the cleaner on the electrical contacts and get a clean cloth to wipe the electrical contacts. The spray content should soften the contamination, and then you can always find it easy to clean and keep the electrical contact clean and neat.
Electrical contact cleaner substitute
There are alternatives to contact cleaner spray products out there in the market that you can consider. You can clean your electrical contacts with any substitute such as acetone, Isopropyl alcohol, WD40, and vinegar.
Acetone, also known as nail polish remover, is a highly effective solvent for cleaning electrical contacts. It dissolves much of the grime that accumulates on guitars during use, and it dries even faster, leaving no residue, just like pure isopropyl alcohol.
When using isopropyl alcohol as a contact cleaner, use the purest grade possible. Search for 99 percent IPA (isopropyl alcohol). This type of alcohol dissolves various contaminants, including skin oils, nicotine deposits, dead skin, and more. 99.9% Pureness IPA cleans effectively and quickly, which is ideal for an electrical contact cleaner.
Although WD40, a lubricant and water dispersant, can loosen and dissolve grime, it will leave a significant amount of residue and a greasy lubricant film. This will act as a magnet for dirt, likely exacerbating the problems you’ve already encountered.
Vinegar is a mild acid that can be used for various cleaning purposes, but it takes a long time to dry. If you leave any moisture behind and it hasn’t dried by the time you plug in the guitar again, you risk creating shorts that will cause serious damage to the electrical components.
